Procurement Notes
Verify the specific datasheet version when sourcing, as Mini-Circuits may update electrical specifications or mechanical drawings over time. Confirm that the 0603 footprint matches your PCB layout requirements. Ensure the supplier provides genuine Mini-Circuits products to guarantee the stated 2.2 dB insertion loss and 13.9 GHz cutoff performance. Check for any RoHS compliance markings if required by your manufacturing standards.
Selection Notes
Select this component when a compact low pass filter is needed for frequencies up to 13.9 GHz. The 0603 package size suits space-constrained designs. Consider the 2.2 dB insertion loss against system power budgets. Verify compatibility with 50 ohm system impedance. LTCC technology offers stability for microwave applications requiring reliable signal attenuation above the passband.
